Analysis of the cold compaction behavior of titanium powders: a comprehensive inter-model comparison study of compaction equations

Author: Machaka, Ronald ; Chikwanda, HK Date: May 2015 A brief background to compaction equations and their application to titanium powder is presented. The behavior and mechanisms of densification in selected titanium powders is critically analyzed by means of a comprehensive inter-model comparison ... Read more
Reinforcement of 2124 Al alloy with low micron SiC and nano Al2O3 via solid-state forming

Author: Gxowa, Z ; Camagu, ST ; Govender, S ; Pereira, MF Date: Jul 2015 A powder metallurgical process was used to fabricate Metal Matrix Composites (MMCs). A 2124 aluminium alloy was reinforced with 5 and 10 vol. % of Al2O3 (40-70nm) to form Metal Matrix Nano Composites (MMNCs) as well as 10 and 15 vol. % of SiC ... Read more
Rheological assessment of titanium MIM feedstocks [Conference paper]

Author: Benson, JM ; Richter, W ; Chikwanda, HC Date: Oct 2010 Titanium is an exciting structural material that can offer significant strength-to-weight advantages over currently used alloys. However its Achilles heel is its cost energy intensive production process that effectively eliminates it from ... Read more
Ti-Pt Alloys form mechanical milling

Author: Nxumalo, S ; Chikwanda, HK ; Machio, Christopher N Date: Dec 2009 The high temperature ß-TiPt phase has been shown to undergo a martensitic transformation upon quenching to room temperature. The martensitic transformation results from a transformation of the parent B2 cubic structure to the martensitic B19 ... Read more
